Depending on their construction, these floors are either monobloc (e.g. structures made of a single frame, carpets).
[4][5][6] The first sensing floor prototypes were developed in the 1990s, mainly for human gait analysis.
Such floors are usually used as a source of sensing information for an ambient intelligence.
Depending on the type of sensors employed, sensing floors can measure load (pressure), proximity (to detect, track, and recognize humans), as well as the magnetic field (for detecting metallic objects like robots using magnetometers).
[10] Notable examples of sensing floors have been developed by Oracle,[5] MIT,[6] and Inria.
